I can attest to only a few of the most powerful engines in my collection, and some are no longer available.
From Plarail, the Hyper Guardian Cargo and Trans Liner engines are sheer powerhouses with speed; both could easily haul a train in excess of 20+ cars, but I've never dared due to space constraint in actually testing it.
Another from Plarail is the HD300, which is just a tad slower than the other engines, but what it lacks in speed it makes up for in brute strength.
From the Plarail Thomas & Friends line, Murdoch, Oliver, and Neville (mine known as "Stephen the Q1") are the most powerful ones in my fleet; surprising as Oliver is a tank engine, but a welcome surprise nonetheless.
From HiT Toys TrackMaster, Donald, Douglas, and Hank are my powerhouses from that range; the Scottish twins' motors are already noisy, but grow noisier still when given a long consist. Kind nice that it emanates real-life of an engine snorting noisily to move its train.
From Fisher-Price TrackMaster 1.0, Ferdinand is the only one who is fairly strong in his own prospect; he's the only engine who can really haul a long train without struggling or choking up on a straightaway.
From Fisher-Price 2.0, none of the engines in my fleet are powerful; they are shamed in speed against the Hyper Guardian Trans Liner and Cargo Liner, and same goes with hauling capacity.
****ADDED****
As jdogman has mentioned, the TAKARA TOMY Plarail/TOMY USA Thomas and the Jet Engine Thomas has a faster motor, which allows more hauling capacity; this makes the gears choke up, depending on length of train and weight, as the engine is made simply for rocketing along the line.
With HiT Toys TrackMaster and Fisher-Price TrackMaster 1.0, it can be difficult to finesse which engines are powerhouses and not; the motors can be picky on the battery brand that you put into them. For example, my HiT Toys TrackMaster Spencer will, somehow, purposely run slowly on a fresh Duracell battery while either of the Scottish Twins will thunder with any consist given to them; Fisher-Price Den may be sluggish with a fresh Energizer battery (<-- Ironic, isn't it?) but may speed along with a fresh dollar store brand.
